Fork in Coroutine (Swoole\Error: must be forked outside the coroutine) #2716
Description
swoole 4.4.2 默认开启了协程，不允许在协程环境下 Swoole\Process->start()，造成之前的代码不兼容，有什么好的办法？全局禁用协程也不行
swoole-jobs之前基于\Swoole\Timer::tick下调用Swoole\Process实现，代码见这里：
[Swoole\Timer::tick]](https://github.com/kcloze/swoole-jobs/blob/master/src/Process.php#L252)
[Swoole\Process](https://github.com/kcloze/swoole-jobs/blob/master/src/Process.php#L152
